Black (pp. 319-320) notes that this is the only occurrence of the word analytischen in the Tractatus, and suggests that it probably does not mean “true by definition” or “true in virtue of the meanings of its component words” here, nor have its original, Kantian sense, but rather is here simply a synonym for “propositions that say nothing.”
